IMPROVEMENT IN PLAlTlNG-MACHINES.

Specification forming part of Letters Patent No.

179,763, dated July 11, 1876 application led April 21,1876.

Y To all whom it may concern:

Beit known that I, J cHN HAMILTON BROWN, of the city, county, and Stateof New York, have invented Ycertain new and useful Improvements inCrimping-Machines, of which the following is a specification:

The object ot' my invention is to produce a machine which shallbe simplein action and accuratein operation, for making trimming for ladieswearingapparel; and consists ot' the mechanism hereinafter described.

Figure lis an end view. Fig. 2 is a top view. Fig. 3 is a sectionalview. Fig. 4 is a front view. Y

A is the bed plate. B B are the sides ofthe frame. O is thedriving-shaft. D is an adjustable eccentric for regulating the feed. Eis the crank for operating the crimping-blade b. F is the connecting-rodfor conveying motion to the crimping-blade. G is a lever for governingthe action oi' the crimp-former on the material. H is a rock-shaft, towhich the crimping-blade is attached. I I l are tension bars, throughwhich the material is passed before crimping. J is a shaft, to which twoarms, a a., are secured, said arms a a, forming bearings for rock shaftH. K is the top or the feeding-roller. L is the gas-pipe for heating thelower roller X. M is a connecting-rod for conveying motion from the ad,-justable eccentric D to the feed-lever N. O is a pawl for operating theratchet-wheel P. q is a spring for holding the pawl to theratchetwheel.- It is an eccentric shaft for detaching the top or feedingroller K from the heated lower roller X. S is the lcvcr for operatii'igthe eccentric shaft R. T T are bars for holding the sides of the frametogether. U U are springs, which convey a pressure through the levers VV to the feed-roller K. Yis a spring for producing a friction on theshaft J, for the purpose of allowing the crimping blade to press on thematerial before any forward action of the crimping-blade takes place. dcl d d are holes in the crank E and. connecting-rod F, for regulatingthe width of the crimp. eis a shield for protecting the lower rollerfrom gas, soot, or dirt.` fis a set-screw for securing the adjustableeccentric D in position. s is an extension of lever a, against which thelever G strikes, causing the return movement ofthe crimping-blade b. Thematerial to be crimped is passed through'the tension-bars I I l, andbetween the crimping-blade b-and heated roller X. When motion is givento the driving-shaft O, the crimping-blade b receives ai'orward and backmotion from the crank E and connecting-rod F.. In the forward motion theblade I) presscs the material firmly on the roller X, a forward movementof the crimper takes place, making a crimp of thedesired width, which isforced between the rollers X and K, which are held in contact bypressure from the springs U U. The crimp being now formed, thefeed-rollers receive inotion from the eccentric D and ratchet-wheel P,carrying the crimp through the rollers. The crimping-blade returns toits starting-point to form another crimp. l

I have now fully described my invention, and the manner of carrying itinto effect.

What I claim, and desire to secure by Letters Patent, is-

`1. In a plaiting-machine, the adjustable eccentric D, for operating the`leed mechanism, substantially as described.

2. The combination of the detaching-levers V V, springs U U, and shaftli, substantially as described.

3. The rock-shaft J, passing throughl the roller X, in combination withthc arms a a, and blade-shaft H.
